我需要找到一种方法来汇总文件中特定列的所有整数值，并打印其结果。这是我的文件的一部分:
<<< The program found 0 rare variants for the gene ARIH1 for this HEALTHY_CONTROL <<<
<<< The program found 0 rare variants for the gene ARIH1 for this HEALTHY_CONTROL <<<
<<< The program found 1 rare variants for the gene ARIH1 for this HEALTHY_CONTROL <<<
<<< The program found 0 rare variants for the gene ARIH1 for this HEALTHY_CONTROL <<<
<<< The program found 0 rare variants for the gene ARIH1 for this HEALTHY_CONTROL <<<
<<< The program found 2 rare variants for the gene ARIH1 for this HEALTHY_CONTROL <<<
<<< The program found 0 rare variants for the gene ARIH1 for this HEALTHY_CONTROL <<<
<<< The program found 0 rare variants for the gene ARIH1 for this HEALTHY_CONTROL <<<
<<< The program found 2 rare variants for the gene ARIH1 for this HEALTHY_CONTROL <<<
<<< The program found 0 rare variants for the gene ARIH1 for this HEALTHY_CONTROL <<<
<<< The program found 1 rare variants for the gene ARIH1 for this HEALTHY_CONTROL <<<
我想打印第 5 列的总和，即稀有变体的总数。在这个例子中，它应该打印 6。
我尝试了以下命令(没有用):
grep "rare variants for the gene ARIH1" fileName | tail -n+2 | awk -F " " '{sum+=$5} END {print sum}'
此命令打印 1，这是错误的。
我该怎么办？谢谢!
